I found a file named 'libMonitorX86Emu.dylib' inside Parallels Desktop 20, and I found that it should be a FEX (a very popular x86 user space emulator under ARM Linux and RISC-V Linux) fork by doing some static analysis... It doesn't seem that Apple will drop Rosetta 2 on Apple Silicon Macs in few years, even their Game Porting Toolkit based on Rosetta 2 and Wine, so what is the'libMonitorX86Emu.dylib' for? A system-level x86 OS emulation on the way? Is that cause the delay of release of Parallels Desktop 20?
